Why we use cookies

We use cookie tracking data to make informed decisions on whether the site is meeting your needs, which leads to us making improvements. For example, we monitor how much traffic each part of the site gets and work to improve areas which are not being found when they should be.

The cookies that we set on can not be used to identify you personally. Find out more about how to manage cookies for all websites

Turn cookies on or off

We use 3 main types of cookie on our website. You can choose which cookies you’re happy for us to use. Any data collected is anonymous.

Google Analytics

We use Google Analytics to collect information about how you use

We store information about:

  • the pages you visit and how long you spend on each page
  • how you got to
  • what you click on while you’re visiting

We do not:

  • collect information that can be used to identify you; for example, we never receive your name or address
  • make any attempt to find out the identities of people visiting
  • allow the tools that we use to find out the identities of people visiting
  • sell, trade or give your details to third parties, unless we are required to do it by law

All information we get through cookies and analytics will be treated in confidence.

We anonymise the last 3 digits of all user IP addresses for Google Analytics, so that we can ensure that you are protected (you can read more about how this works here). We can only see a general overview of which regions and cities you may come from, not where individuals access from.
